A vEN'rmATING A'rrficmmm Foa i PaEssmG MACHINES l 13 Claims.

Heretofore in pressing machines for garment and laundry purposes, whichhave press elements between which the articles are pressed, the heatingmedium supplied to one of the elements causes the temperature in.proximity to the machine, and at the places necessary to be occupied bythe operator, to be very high, thereby rendering working conditions verydisagreeable and uncomfortable.

It is one of the objects of the present invention to overcome thesediiliculties, objections, and inconveniences and to provide an improvedattachment for apressng machine of this character, which will remove theheat from the place which the operator occupies and thereby 'providemore comfortable working conditions.

The invention consists further in the provision oi a hood for themovable press member, which latter is usuallythe heated member, andwhich hood is secured to and is movable therewith, the hood being soconstructed and arranged as to provide an inlet opening or slotencompassing the edge of the movable press member, and being providedwith a. discharge outlet, means being associated and carried with thehood for inducing a circulation of the air through the hood and aroundthe pressing members, to be discharged vfroml the hood and directed awayfrom the operator.

A further object is to provide an improved at- I tachment of thischaracter which forms a part of the movable press member, so that thepressing machine may be readily shifted and moved into another positionto permit re-arrangement vof the machine, without interfering with thehood or its associated intact.

'To the attainment/of these ends and the accomplishment of other new anduseful objects as will appear, the invention consists in the featureaofnovelty in substantially the construction, combination and arrangementof the several parts hereinafter more fully described and claimed andshown in the accompanying drawing illustrating this invention, and inwhich Figure 1 is a side elevation of a portion of a pressing machine ofthis character,` having r'a' Ventilating attachment connected therewith,constructed in accordance with the principles of this invention.

I Figure 2 is a top plan view of the parts shown in Figure 3.

Figure 3 is a sectional view taken on line 3 3, Figure 2.

Referring more particularly to the drawing,

parts, lall of which remain the invention is shown in connection with apressing machine which is diagrammatically i1- lustrated, the numeral Idesignating generally the machine frame having a stationary member IIsupported thereby and a movable pressing 5 member or buck I2 carried byanvarm I3 piv otally supported at I4 to an 4arm or bracket I5 extendingfrom the machine frame. The arm I3 has' an operating handle IB and acounterwelght Il connected thereto and with a counterbalancing springI8.

All of these parts are of the ordinary and well known construction andas before indicated, are merely illustrated diagrammatically to show oneform of pressing machine with which this invention can be used.

The invention consists essentially of a hood I9 constructed of anydesired or suitable material, preferably of sheet material shaped intothe proper form to provide an open side and a 20 reduced portion 2| toform a fan chamber 22 which connects with the inside of the hood, and

v the fan chamber is provided with a discharge outlet 23.

This hood may be of any desired coniiguration, but is constructed to besomewhat larger than the movable head or pressing member I2 and issecured in position and supported for movement with the movable head inany desired or suitable manner, such as by means of brackets 24, so thatwhen the movable member I2 is raised and lowered, the hood I5 will beraised and lowered therewith.

The movable member I2 is supplied with a heating medium in the usualmanner, such as by means of pipes 25 and the hood I9 is of such a sizeto provide an open slot 26 around the edge of the movable head or memberI2 and the skirt of the hood may, ii.' desired, be of a length that itwill extend below the upper surface of the stationary 40 member II ofthe pressing machine.

Within the fan chamber 22 is located a fan 21 which preferably ismounted to rotate about an' upright axis 28, the latter being the shaftof a motor 29 which is also arranged within the fan 45 casing or housing22. This fan and motor preierably constitute a unit and are supported inposition in any desired or suitable manner, such as by means of supportsor brackets 30 carried by the hood.

The fan 21 is preferably arranged adjacent the outlet opening 23 and ascreen or reticulated member 3| covers the opening 23 so as to protectthe fan.

With this structure it will be manifest that the 55 hood becomes anintegral part of the press and particularly of the movable pressingmember or headv I2.

The motor is operated in any desired or suitable manner, that is currentis supplied thereto by means of the conductors 32 leading from asuitable source of supply of current.

' Obviously, the fan chamber 22 may be of any desiredconguration and thefan may be propelled by any suitable means, but preferably by means ofan electric current and the motor is preferably electric.

In operation and when the parts are in the position shown in Figure 3,the fan 21 rotates in such a direction as to cause a draft of air toenter the slot 26 between the movable head and the lower edge of thehood, preferably encompassing the movable head and a portion of thestationary head when the movable head and hood are lowered, and willbe'expelled-through the discharge opening 23 in the top of thev hood orin'` the fan chamber 22, thus drawing the heat away fromthe personoperating the press and forcing it out through the top of the hood,where it may rise to the ceiling and may be removed or withdrawn bysuitable exhaust fans or any other suitable means.

With this construction it will be manifest that the hood will not be inthe way of the operator and will be moved upwardly and downwardly ortoward 'and away from the stationary pressing member I I with themovable head. At the same time the fan will be constantly operating andwill draw the heated air into the hood and discharge the same throughthe outlet opening 23 away from the operator, thereby providing morecomfortable working conditions for the' operator.

The fan being continuously operated, will also continue to draw away theheated air from the operator even when the movable member and hood areraised.

y(With this construction it will also be manifest that the motor, i'anAand hood become an integral part of the machine, the only outsideconnections being the conduits for conducting the current to the motor,if an electric motor is employed, or the conduits for supplying thenecessary power when an hydraulic or other iiuid actuated motor is used,and with this construction it will be manifest that the machine can bereadily shifted inl its position upon the door so as to permitrearrangement of machines when desired, without the necessity of havingto dismantle any couplings or outside connections.

While the preferred form of the invention has f been herein shown anddescribed. it is to be understood that various changes may be made inthe details of construction and in the combination and arrangement. ofthe several parts, within the scope of the claims, without departingfrom the spirit of this invention.
